It's cool that you're trying to make stuff, but you should be coming up with your own original ideas instead of "remaking" someone else's. And you should realize that it isn't realistic to expect a full team of artists and programmers to work with you unless either 1. you're already friends and/or collaborators, or 2. you're willing to pay them for their work.
I totally understand the excitement and ambition of trying to do a big project with lots of collaborators right off the bat, I tried to do similar things and made similar threads myself when I was (I'm assuming) your age, but it's putting the cart before the horse and ultimately it will never get you anywhere.
If I were you I would try to focus on smaller, original projects you can do by yourself. That way you'll actually have some experience developing your skills and some finished products you can show to potential collaborators so they know you're capable. Have fun with it!
